Txhawm rau nthuav dav ib ntu ntawm DNA siv PCR, tus qauv yog thawj zaug kom cov DNA denatures, los yog cais ua ob daim ntawm ib leeg-stranded DNA. Tom ntej no, ib qho enzyme hu ua " Taq polymerase " synthesizes - tsim - ob tug tshiab strands ntawm DNA, siv cov thawj strands ua templates.
Dab tsi tshwm sim thaum lub sijhawm PCR amplification?
Kev nthuav dav yog ua tiav los ntawm peb kauj ruam: (1) denaturation, nyob rau hauv uas ob-stranded DNA templates yog rhuab los cais cov strands; (2) annealing, uas luv DNA molecules hu ua primers khi rau flanking cheeb tsam ntawm lub hom phiaj DNA; thiab (3) txuas ntxiv, uas DNA polymerase txuas ntxiv 3′ kawg ntawm txhua…
Puas PCR siv rau kev nthuav dav?
PCR yog siv rau hauv molecular biology rau ua ntau daim ntawv luam ntawm (amplify) cov ntu me me ntawm DNA? lossis cov noob?. Siv PCR nws muaj peev xwm tsim tau ntau txhiab mus rau tsheej lab ntawm cov ntawv luam ntawm ib ntu ntawm DNA los ntawm ib qho me me ntawm DNA. PCR yog ib qho cuab yeej siv hauv kev tshawb fawb txog kev kho mob thiab tshuaj lom neeg.
Puas yog PCR gene amplified?
